BROODER.

Application filed. August 2c, 1920. semi nbl rears-"1.

2' 0 all 107: o'm it may concern:

Be it known that T, liLinY (:LASE BARON,

a citizen of the United States, residing at Hampden Meadows, 1n the county of Br1 ol adapted to be heated by a circulation of hot' water in an over-head tank; and is an im pr'ovem'ent on my prrorlatent No; 1,329,491},

' dated February 3, 1920. V

The invention further consists 111 the arrangement of a window through which a thermometer inclosed within the brooding space maybe readily observed for the purpose of determining the internal. temperature of the brooder without withdrawing the curtains.

.With theseando'ther objects in view, the invention'consists of certainnovel features of construction, as will be more fully described, and particularly pointed out in the appended claim.

In the accompanying drawings:

Figural is a plan view of my improved brooder, partly broken away to better illu trate the position and shape of the heating tank within.

Figure 2 is a central sectional elevation of my improved brooder.

Figure 3 is a retail illustrating the means for suspending the thermometer in the brooding chamber'whereby it may be readisy moved up to the windowto be better ob served.

Referring particularly to the drawings, it will be observed that the brooder is shown as being substantially circular, that is, covering a circular area. 10 indicates a relatively flat horizontal water tank or radiator for the brooder and is preferably formed substantiallyin the shape of a lengthwise middle section through a pear, that is, it is provided with an enlarged circular body'portion 11 having a lateral extension 11, the side walls 13 of which extension extend tangentially of the body portion 11 and meet at their outer ends, as indicated at 12. The upper and lower body plates 14: and 15 of this tank are spaced apart a short distance providing a tank adapted to carry a comparatively thin body of water and extending the same over a relativelyj large area, .the'

tank being disposed in a 'horiz'ontal position. 7 This tainkis supported a siiitzible distance from the floor 16 onlegs'17.

in order to' facilitate the heating" of the vater in this tank, I haveprovided a drop-1 leg 18 wh ch 1s preferably in cylindrical rorm pro ect1ng downwardly from 'thelaten.

ally-extending portion the tank and through the center of this leg, I have provided'a heat-conducting flue 20 at thelower end of which the burner 21 is placed. The

upper end 22 of this flue is arranged to open into'the air super heating drum 23. The burner 21 maybe either a lamp, oil as" or any other heat-producing device.

In order to facilitate the circulation of the heated water through thebody portionf or the heating tank, 1 have provided a jacket 2 about this heat flue" which has openings 25 at its lower end to admit the water and is opened at its upper end to permit the heated column of water to flow outwardly. near the top of the tank and so cause a circulation of the heated water through the body of the tank.

It is found in practice in a plain tankthat the large body of water about the center of the largest diameter of the tank, serves to over heat the middle portion of the brooder, which is detrimental, andto obviate this difficulty, I have provided an'opening'27.

at this point through the body portion of;

this tank, which openingis of a substantial size, in some instances approximately that ot one-third the greatest diameter of the body ofthe tank, but I do not wish to be restricted to this exact size as the diameter oi" this opening may be varied with the conditions under which the device is operated.

In order to receive and deflect the heat from the tank, downwardly into the brooding space below, I have provided a hood member 28 which has a top plate spaced a short distance above that of the heating tank providing an upper air space 29 between them. The periphery 30 of this hood is preferably beveled or set on an incline to better deflect the heat downwardly into the space below. This hood may be supported from the tank by means of spacers 31.

About the edge of this hood I have positioned curtain rods 32 on which are supported curtains 33 which may be made of any suitable material such as thin oilcloth or the like, which curtains drop down like a skirt from the outer edge of the hood inclos ing the brooding space and retaining the heat within. The lower edge of this curtain is proper circulation of both fresh and heated air for thelittle ones, I have provided one or more openings 35 of any convenient shape through these curtains to supply this light and needed air and I have preferably placed these openings in the curtains at a point above the heads of? the chicks so that the in-' ward draft therethrough will not be detri mental to them.

In order that the temperature of the interior of the inclosed brooding space may be readily ascertained without withdrawing the curtains, I have suspended a thermometer 36 by a wire 37 from the hood in this space. Two windows 38 areiormed in the curtains one on each opposite side of the brooding space and I have positioned a thermometer which is preferably of the transparent type, at a point intermediate these two opposite windows whereby by looking into either of these windows the thermometer may be readily observed by'the light which is admitted through both. To further facilitate the reading of the thermometer l. have formed a handle 44 on the outerend of the suspension wire 37 whereby the instrument may be swung laterally up close to the window for better observation.

The operation of my improved brooder may be more fully described as follows: The circulation of the heated water through the body of the tank is facilitated by the use of a jacket 24: about the heating flue, and the opening at the middle or center portion of the brooder avoids the over-heating of the air at this middle portion, and this opening through the tank also cooperates with the opening 35 in the curtain to draw in fresh air and create a constant circulation of fresh heated air through the broodingchamber.

After the air within the brooder has been raised to a predetermined temperature the usual regulating damper 39 is raised, by means of the usual thermostat 40, located within the brooding chamber, through the pivot arm 41 to uncover an opening in the hood aligned with the opening 27 of tank 10.

As theheat from the drop leg 18 is more or less intense I have positioned a wall 42 between it and the brooding chamber to prevent local overheating ot' the'broodingspace and this wall is positioned a short distance inwardly fromthe wall of the drop leg providing an air space 43 between them for further modifying the local heat within the brooder.

My improved brooder is extremely simple and practical in construction and effective in its operation and by its use a very even temperature may be maintained throughout the brooding space and a constantcirculation of air created therein.

The foregoing description is directed.

solely towards the construction illustrated,

but I desire it to be understood that I reserve the privilege of resorting to all the mechanical changes to which the deviceis susceptible, the invention being defined and limited only by the terms of the appended claim. 1

I claim: V

In a brooder, a brooding chamber. a thermometer of the transparent typewithin said broodingchamber. oppositely arranged light openings in said chamber, said thermometer being positioned between said openings whereby it may be readily observed through one opening and the light admitted through the other opening permitting a reading thereof.

In testimony whereof I affix my signature.
